Super Dual Auroral Radar Network

SuperDARN site in Holmwood SDA, Saskatoon

The Super Dual Auroral Radar Network (SuperDARN) is an international radar network for studying the upper atmosphere and ionosphere, comprising twenty one radars in the northern hemisphere and eleven in the southern hemisphere [1] that operate in the High Frequency (HF) bands between 8.0 MHz (37m) and 22.0 MHz (14m).

The Java applets that are used as the radar data display system currently indicate the 10 MHz (30m) and 14 MHz (21m) frequency bands as being primarily used in 2012 (in the Northern Hemisphere). The radars measure the Doppler velocity (and other related characteristics) of plasma density irregularities in the ionosphere.

In the standard operating mode each radar scans through 16 beams of azimuthal separation ~3.24°, with a total scan time of 1 min. Each beam is divided into 75 range gates of length 45 km, and so in each full scan the radars each cover 52° in azimuth and over 3000 km in range, an area of over 4×106 km².


SuperDARN began in 1983, when the first radar installation was constructed in Labrador, Canada.[2]

Additions to the ionospheric RADAR network (in the Northern and Southern Hemispheres) have occurred about once every 4 years.

Since Linux became popular, it has become the default operating system for the Superdarn network. The operating system (superdarn-ros.3.6) is currently licensed under the LGPL). [1]

SuperDARN sites

The following is a list of SuperDARN sites, based on lists maintained by Johns Hopkins University Applied Physics Laboratory,[3] University of Saskatchewan,[4] and Virginia Polytechnic Institute and State University.[5] As of 2009, the network is expanding to the middle latitudes, including sites in Hays, Kansas (near Fort Hays State University), Oregon, and the Azores, in order to support mapping outside of the auroral regions during large magnetic storms.[2]

Northern Hemisphere

  • Because the SuperDARN network evolved in the west during the late Cold War, coverage of Russia's arctic regions is poor.
  • Although there is no shortage of possible sites to cover Russia's arctic regions from Northern Europe and Alaska, the coverage would probably not be of high quality.
  • So far there has been no movement within those managing the SuperDARN network to do joint ventures with Russian universities to build the Russian part of the network.

Southern Hemisphere

  • Although Antarctica is covered reasonably well, the Sub-Antarctic regions do not have uniform coverage.
  • Java VM real time display software interoperability (where both poles could be observed at the same time) is still a work in progress.
